Description

High voltage battery for electric vehicle
Technical Field
The present invention relates to a high-voltage battery for an electric vehicle according to the preamble of claim 1 and a method for mounting a high-voltage battery according to claim 10.
Background
A high-voltage battery for an electric vehicle of this type has a housing cover and a housing lower part which together delimit a housing interior. The housing interior space is divided into a cell subspace and a component subspace. A battery cell is arranged in the battery cell subspace and at least one electronic component is arranged in the component subspace. A gas discharge space extends between the cell upper side of the battery cell and the housing cover, into which gas discharge space hot gas flows from the gas discharge outlet of the damaged battery cell in the event of a thermal event in one of the battery cells. Furthermore, electronic components are also acted upon by the hot exhaust gas when a thermal event occurs. The effect of the hot exhaust gas may disadvantageously cause the electronic components to degrade temporarily or permanently.
An exhaust system for a battery module is known from document WO 2016/053404 a 1. Document EP 2581960 a1 discloses a battery pack. A battery module is known from EP 2445032 a 1.
Disclosure of Invention
It is an object of the present invention to provide a high voltage battery in which the performance of electronic components is ensured without being limited when a thermal event occurs.
This object is achieved by the features of claim 1 or claim 10. Preferred developments of the invention are disclosed in the dependent claims.
According to the characterizing part of claim 1, the high-voltage battery has a partition wall which separates the exhaust space from the component sub-space. The partition wall advantageously ensures that the hot exhaust gases do not interact with the electronic components. Therefore, the hot exhaust gas does not affect the functionality of the electronic component.
In a preferred embodiment, the separating wall can be a middle partition, which can extend in the horizontal device plane between the housing cover and the cell top side of the battery cell. This has the advantage that a high-voltage battery with battery cells arranged upright can be retrofitted with the intermediate floor in a simple manner.
Preferably, the intermediate partition can have at least one exhaust channel, the opening edge of which can be supported on the upper side of the cell. Additionally, the opening edge may surround at least one monolith-side exhaust outlet. By means of the defined exhaust duct and the support of the opening edge on the upper side of the individual body, a sealing between the exhaust space and the component sub-space is achieved in a structurally simple manner. This has the advantage that the hot exhaust gas is conducted directly, i.e. without flowing into the component sub-spaces, into the exhaust gas space and is discharged from there into the battery environment.
Particularly preferably, the opening edge of the exhaust gas duct can be supported on the upper side of the single body with the interposition of a sealing element, by means of which the sealing effect between the exhaust gas space and the component sub-space can be increased. The provision of a sealing element has the advantage that the sealing effect between the exhaust space and the component sub-space is enhanced.
In one embodiment, the housing lower part can be provided in the battery assembly in the empty state for the preparation of the installation process, i.e. the housing lower part is not yet installed and is open upward in the housing height direction. In addition, the electronic components and the battery cells can be inserted into the component and battery cell subspaces in the installation direction along the battery height direction during the installation process. Furthermore, the partition wall can be inserted into the housing lower part after the setting process, and the housing lower part which is open at the top can then be closed by means of the housing cover. With this structure and this assembly, the high-voltage battery can be mounted in a small number of mounting steps and thus in an efficient manner.
Preferably, the component sub-spaces and the cell sub-spaces can be positioned side by side in the transverse cell direction in the housing lower part, in particular the venting space can be arranged in the housing height direction between the housing cover and the cell upper side, wherein in particular the partition walls can cover the component sub-spaces. By arranging the exhaust space above the plurality of battery cells in the housing height direction, the overflow of the hot exhaust gas into the exhaust space is advantageously promoted. The positioning of the component sub-spaces between the cell sub-spaces and the housing side walls has the advantage that the cell can be inserted into the cell sub-spaces without interfering with the contour, since the component sub-spaces provide an annular structural space for the assembly of the cell. This is advantageous in particular when the battery cells are packed into a modular unit and inserted into the housing lower part from above when mounting the high-voltage battery in the battery height direction.
Furthermore, the individual elements can also be positioned directly on the housing side wall, depending on the solution. In particular, the positioning of the battery cells in the high-voltage battery is dependent on the installation conditions, the modularity, the component tolerances, the connection technology used and the support of the battery cells. Furthermore, the positioning of the battery cells can be related to the provision of functional structural space, housing options, pretensioning and the operational load of the cells, as well as thermal options of the battery cells. In particular, the mounting position and the mounting tolerance may have an influence on the selection of the positioning in terms of the assembly conditions. With regard to modularity, the grouping of the battery cells and the resulting tolerances and resulting support schemes can affect the positioning of the battery cells. For example, a deformation zone can be used as a functional structural space, which deformation zone prevents the formation of a block structure/plug structure (Blockbildung) in the event of a crash. The housing solution also affects the positioning. In this case, the battery cells can be positioned depending on whether the housing is made of a single piece or is constructed in multiple pieces. Furthermore, the separating plane is important in terms of the housing solution.
In one embodiment, the lower housing part can have a housing base and housing side walls rising laterally from the housing base. Furthermore, the component sub-spaces can be delimited laterally outward by the housing side walls and laterally inward by the cell sub-spaces, as viewed in the cell transverse direction. In addition or alternatively thereto, the intermediate floor can be supported at the edge side on the housing side wall, to be precise in particular with the interposition of an external sealing element. This has the advantage that no hot exhaust gases can escape from the exhaust gas space into the component sub-space in the region of the edge side of the intermediate partition.
Preferably, the exhaust space can be fluidically connected to the cell environment via at least one housing-side exhaust opening. This ensures in a simple manner that the hot exhaust gases can flow out of the exhaust space into the environment surrounding the battery.
Particularly preferably, the battery cells can be designed as prismatic battery cells, which are arranged one behind the other in the stacking direction. Alternatively or additionally, the exhaust outlet can be located on the upper side of the cell and the exhaust outlet can be provided with a rupture disc. Furthermore, a housing-side air outlet can be provided on the housing cover. The arrangement of the exhaust gas outlet on the upper side of the cell has the advantage that hot exhaust gas, which may have a low density compared to air, reliably flows out of the cell in the direction of the height of the battery and counter to the direction of gravity.
In one technical embodiment, the stacking direction may be perpendicular to the cell height direction and extend in the cell lateral direction. Furthermore, a pressure compensation element can be provided in each case not only on the gas outlet space but also on the component sub-space, which pressure compensation element makes it possible to achieve a pressure compensation between the cell environment and the gas outlet space or the component sub-space. Furthermore, the sealing element and the external sealing element may each be a sealing element made of sponge rubber. The exhaust outlet may be provided with at least one rupture disc. In addition, a spark protection device in the form of a glass fiber nonwoven can be provided at the exhaust gas outlet, which spark protection device advantageously prevents sparks from entering the exhaust gas space from the cell sub-space. The separating wall can be a separating wall made of an electrically insulating material and can alternatively form, on the edge side, a double flange connection with the housing cover and the housing lower part, by means of which the separating wall can be clamped to the housing cover and the housing lower part. In a preferred embodiment, the exhaust gas space may be formed by a rocker.
The invention further relates to a method for assembling a high-voltage battery according to the invention.
Drawings
An embodiment of the present invention is described below with reference to the drawings.
The figures show that:
fig. 1 shows a high-voltage battery according to the invention in a sectional view.
Detailed Description
Fig. 1 shows a high-voltage battery 1 with a battery housing 3. The battery housing 3 has a housing lower part 5 which comprises a housing base 7 and housing side walls 9 standing up from the housing base in the lateral direction. A housing cover 11 is placed on the housing lower part 5, which housing cover is screwed to the housing lower part 5 at a threaded point 13. The housing lower part 5 encloses a housing interior 15 together with the housing cover 11.
The housing interior 15 is divided into an exhaust space 17, a cell subspace 19 and a component subspace 21, in which electronic components 23 are arranged. The exhaust space 17 is fluidically connected (i.e. communicates) with the battery surroundings via an exhaust opening 25 in the housing and is arranged above the cell sub-space 19 and the component sub-space 21, based on the battery height direction z. In the cell sub-space 19, prismatic cells 27 (three such cells 27 are exemplarily shown) are arranged, which are arranged in sequence in the stacking direction S. The component sub-spaces 21 and the cell sub-spaces 19 are positioned side by side in the transverse cell direction y in the housing lower part 5, so that the cells 27 delimit the component sub-spaces 21 laterally inwardly. The component sub-spaces 21 are delimited laterally to the outside by the housing side walls 9. The battery cells 27 have a cell upper side 29, on which each of the battery cells 27 is provided with gas outlet openings 31, which together form a gas outlet opening 33 on the cell.
A plate-like intermediate partition 35, which extends in the horizontal device plane E and covers the component sub-spaces 21, is arranged in the housing interior 15, and extends between the housing cover 11 and the cell top 29, so that the exhaust air space 17 is arranged in the housing height direction z between the housing cover 11 and the cell top 29. The intermediate partition 35 has a plurality of perforations 37 which together form an exhaust channel 39. In addition, the intermediate diaphragm 35 has an opening edge 41 which completely surrounds the exhaust gas outlet 33 and which is supported on the monolith upper side 29 with the interposition of a sealing element 43 in the form of a closed ring. The exhaust space 17 is thus sealed in an airtight or flow-tight manner with respect to the component sub-space 21. The intermediate partition 35 is also supported on the housing side wall 9 on the edge side and with the interposition of an external and closed-loop sealing element 45.
In fig. 1, the battery cell 27 shown on the right is shown by way of example as a defective battery cell 27 in which hot exhaust gases are formed as a result of a thermal event T and are discharged along an exhaust gas flow path 47 from the battery housing 3 into the battery environment. For this purpose, the hot exhaust gases first flow out of the battery cells 27 at the exhaust openings 31 belonging to the battery cells 27 and flow into the exhaust space 17 via the exhaust duct 39, while the hot exhaust gases do not flow into the component sub-space 21. The hot exhaust gases are discharged from the exhaust space 17 through an exhaust opening 25 in the housing to the surroundings of the battery.
